| 摘要 |
<p>The present invention relates to a foodstuff base which is intended particularly for consumer packages of fresh meat. The base formed from sheet material by pressing into a basin comprises an upper paper or carton layer 5 provided with a non-adhering, liquid-permeable surface 8, thereunder a liquid impermeable block layer 6 made of polymer, and thereunder a lower carton layer 7. The surface of the base can be calendered or it can be formed from a polymer coating layer 8 provided with liquid-permeable apertures or pores. The permeable surface 8 enables the fluid extracting from a packaged product, such as meat, to absorb into the upper carton layer 5 acting as the absorption layer. The block layer 6 prevents liquid from being absorbed into the lower carton layer 7 acting as the absorption layer. The block layer 6 prevents the liquid from absorbing into the lower carton layer 7 which acts as a dry keeping, stiffening element. <IMAGE></p> |
